[DRL333]

Thanks again for your feedback.

Brenden.

I am glad to come across another "ring bearer". It must have been a shock to you to invest in such an upmarket scope that still has tracking issues. Unfortunatetly, I had not picked up any rumors of that problem on the astro forum prior to me getting one.

According to your interpretation of the problem I should get less problems when the object has reached its zenith where only one drive controls the tracking. If tonight is clear I will check it out.

I did notice that a small puff of wind play havoc with tracking

Tak.
I take your point about about the likely futility of PEC training.
I had not realised that balance would be important for tracking jitter. I have not used any compensation for the camera. the balance is not exact but compared to the weight of the scope the balance is not far off.

thanks again
Derek
